title: [Chemical studies of minor triterpene compounds isolated from the stems and leaves of Panax ginseng C.A. Meyer].
abstract: Two new natural products were isolated from the stems and leaves of Panax ginseng C.A. Meyer cultivated in Liaoning, China. Their structures were characterized as 20(R)-dammaran-3 beta, 6 alpha, 12 beta, 20, 25-pentol and 20(R)-dammaran-3 beta, 6 alpha, 12 beta, 20, 25-pentol-6-O-alpha-L-rhampyranosyl(1----2)-O-beta-D-gluc opy ranoside.
